Yucca plant named 'TUSZYUC001'
A new yucca plant which has abundant flowers and attractive foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.
Botanical designation: Yucca gloriosa.
Variety denomination: ‘TUSZYUC001’.
SUMMARY OF THE INVENTIONThe present invention constitutes a new and distinct variety of yucca plant which was discovered in a cultivated area in Warsaw, Poland. The new yucca variety resulted from a naturally occurring mutation of unknown causation on a branch of Yucca gloriosa variegata, a non-patented variety. The resulting mutation was selected and evaluations were conducted on the resulting yucca plants in a controlled environment.
The yucca plant of the present discovery has a unique combination of characteristics which are outstanding in the new variety and which distinguish it from the original yucca Yucca gloriosa variegata as well as all other varieties which we are aware of. For example, ‘TUSZYUC001’ has marginal intonations on the leaves the color of Greyed-Orange Group 177A and Red-Purple Group 58B. The original Yucca gloriosa variegata has marginal leaf coloration of primarily Yellow Group 4D. Additionally the new variety is more compact than the original variety.
The criteria used to evaluate the claimed plant were selected in order to introduce a distinct variety for garden and container use with unique qualities, such as:
-
- 1. Uniform and abundant foliage with unique purple brown coloration;
- 2. Vigorous, but compact growth when propagated in-vitro;
- 3. Exceptional disease resistance.
This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventor, and distinguish ‘TUSZYUC001’ from all other varieties of which we are aware.
Asexual reproduction of ‘TUSZYUC001’ by basal shoot cuttings in vitro was first done by Grzegorz Tuszynski in Warsaw, Poland in July of 2011. Plants were deflasked and rooted in ordinary peat-based growing medium. This initial and other subsequent propagations have demonstrated that the characteristics of ‘TUSZYUC001’ are stable and reproduced true to type in successive generations of asexual reproduction.
The accompanying color illustrations show as true as is reasonably possible to obtain in color photographs of this type, the typical characteristics of the buds, flowers, leaves, and stems, of ‘TUSZYUC001’. Specifically illustrated in
The following is a description of ‘TUSZYUC001’, as observed in its growth in in a glass house in Warsaw, Poland. Observed plants are 2 years of age and grown in 24 cm containers. Color references are made using The Royal Horticultural Society (London, England) Colour Chart, 2001, except where common terms of color are used.
For a comparison, physical characteristics of the yucca variety Yucca gloriosa ‘variegata’ are compared to ‘TUSZYUC001’ in Chart 1.
